Animation: The World’s Largest Megacities by 2100

Throughout the course of human history, the biggest cities have always seemed impossibly large.

For many millennia, it was almost unfathomable for a city to sustain more than 1 million residents. In fact, it wasn’t until the 19th century that the largest cities globally, such as London and Beijing, were able to consistently hold populations beyond that impressive mark.

Despite this, in the modern era, we’ve quickly discovered that a city of 1 million people isn’t remarkable at all. In China alone, there are now over 100 cities with a million people today – and as such, our mental benchmark for what we consider to be a “big city” has changed considerably from past times.

Thinking Big

Just like a city the size of modern Tokyo was hard to imagine for someone living in the 19th century, it can be an extremely difficult thought experiment for us to visualize what future megacities will look like.

Researchers at the Global Cities Institute have crunched the numbers to provide us with one view of the potential megacities of the future, extrapolating a variety of factors to project a list of the 101 largest cities in the years 2010, 2025, 2050, 2075, and 2100.

Today’s video uses this data – it’s also an extension to the previous work we did based on the report here.

The Largest Megacities by 2100

According to the report, human geography will look completely unfamiliar by the turn of the century.

Here is a list of the 20 largest megacities projected for 2100:

RankPopulation (2100)CityCountry
#188.3 millionLagosNigeria
#283.5 millionKinshasaDRC
#373.7 millionDar Es SalaamTanzania
#467.2 millionMumbaiIndia
#557.3 millionDelhiIndia
#656.6 millionKhartoumSudan
#756.1 millionNiameyNiger
#854.3 millionDhakaBangladesh

#1740.0 millionManilaPhilippines
#1837.7 millionLusakaZambia
#1936.4 millionMogadishuSomalia
#2035.8 millionAddis AbabaEthiopia

By the year 2100, it’s estimated that 13 of the world’s largest megacities will be located in Africa. Meanwhile, India will hold three of them – and there will be zero of them found in the Americas, China, or Europe.

Here’s a final look at the top three:

#1: Lagos, Nigeria
Nigeria’s largest city, Lagos, is expected to push the limits of how big a metropolis can get. Already, Lagos has seen explosive growth over the past few decades, and is growing so fast that no one really knows how many people live there. Over 2,000 people emigrate to the city every day, and current population estimates vary widely from 11 to 21 million inhabitants.

Either way, by the turn of the century, Lagos is projected to have a population north of 88 million.

#2: Kinshasa, DRC
Kinshasa, the capital of the Democratic Republic of Congo is projected to be the second largest city in the world with a population of 83 million.

#3: Dar Es Salaam, Tanzania
Dar Es Salaam, a city on the coast of Tanzania, has a population of just 4.4 million today. By 2100, its population is projected to jump by a whopping 1,588%, putting the total at 74 million inhabitants.

The 10 Most Populous U.S. Cities, Every Decade Since 1790

How has the list of the most populous U.S. cities changed over time? This infographic shows the top 10 cities of every decade since the year 1790.

The 10 Most Populous U.S. Cities, Every Decade Since 1790

There are only two cities that have had the distinction of being named the most populous city in the United States.

The first city to hold the title was Philadelphia, as the City of Brotherly Love was estimated to be the biggest city in the country at the time of the signing of the Declaration of Independence.

However, by the time of the first U.S. Census in 1790, New York City had surpassed Philadelphia by a few thousand residents – and the Big Apple has stayed the largest in the country ever since.

From Then to Now

Today’s infographic comes to us from Liberty Cruise, and it ranks the 10 most populous cities in the United States for every decade since 1790.

To start, let’s take a look at what the list looked just after the first U.S. Census in 1790:

RankCityPopulation (1790)
#1New York City, NY33,131
#2Philadelphia, PA28,522
#3Boston, MA18,320
#4Charleston, SC16,359
#5Baltimore, MD13,503
#6Northern Liberties Township, PA9,913
#7Salem, MA7,921
#8Newport, RI6,716
#9Providence, RI6,380
#10Marblehead, MA5,661

It’s pretty surreal to think that some of the biggest cities in the late 18th century hosted no more than 6,000 residents.

It also may be a surprise to many that Rhode Island – a state that ranks 50th in size and 44th in population today – held two of the largest towns in the nation at the time: Newport and Providence.

The Modern List

Jump forward over 200 years, and New York City has not lost its top spot.

It helped that NYC was able to absorb Brooklyn – one of the country’s other largest cities – into its boundaries in 1898. Other major cities saw similar merges happen over the years, with Philadelphia absorbing Northern Liberties Township, for example.

Here is a list of the most populous U.S. cities in 2017 (est.):

RankCityPopulation (Est. 2017)Population (2010 Census)Change
#1New York City, NY8,622,6988,175,133+5.47%
#2Los Angeles, CA3,999,7593,792,621+5.46%
#3Chicago, IL2,716,4502,695,598+0.77%
#4Houston, TX2,312,7172,100,263+10.12%
#5Phoenix, AZ1,626,0781,445,632+12.48%
#6Philadelphia, PA1,580,8631,526,006+3.59%
#7San Antonio, TX1,511,9461,327,407+13.90%
#8San Diego, CA1,419,5161,307,402+8.58%
#9Dallas TX1,341,0751,197,816+11.96%
#10San Jose, CA1,035,317945,942+9.45%

In contrast to the NYC of today, the 1790 population looks more like a Long Island suburb.

This rapid urbanization is mainly thanks to Industrial Revolution, which triggered a massive migration to cities, allowing New York to grow 26,000% in total population.

Here’s how the population distribution of New York City’s five boroughs has changed over time:

Investing Megatrend: How Rapid Urbanisation is Shaping the Future

By 2050, there will be 2.5 billion more people living in cities than today. How is rapid urbanisation set to impact investors and the global economy?

Published

How Rapid Urbanisation is Shaping the Future

The world is constantly changing, and many of these shifts have the potential to alter the investment landscape.

While some of these changes can be temporary and fleeting, others can be powerful, transformative “megatrends” that shape how society is organized at a fundamental level.

One such megatrend that has been in place for decades is the rapid rate of population growth in urban areas – and while it’s been highly influential thus far, we’ve likely only seen the beginning of its formative impact on the global economy.

An Intro to Rapid Urbanisation

Today’s infographic comes to us from iShares by BlackRock, and it highlights the case for rapid urbanisation as being one of the most important overarching trends to watch in markets over the long term.

It’s a trend that originated in developed economies in the 21st century, as people transitioned from agricultural work to factory and service jobs.

RegionUrban share of population (1900)Urban share of population (2016)
United States40%82%
Japan12%91%
Western Europe41%80%

In these developed economies today, cities are major sources of innovation and wealth creation, and the World Bank estimates that over 80% of global GDP is now generated in cities.

A Global Shift

Over the coming decades, the large-scale role of cities will become even more amplified as rapid urbanisation spills over to the rest of the world.

Billions of people – especially in Asia and Africa – will be seeking opportunities in cities over the coming decades. Between 2018 and 2050, the global urban population will increase from 55% to 68%, adding another 2.5 billion people to cities around the world.

RankCountryUrban population growth (2018-2050)
#1India416 million people
#2China255 million people
#3Nigeria189 million people

Nearly 90% of this growth will be in Africa and Asia, with India alone adding 416 million new people to its cities – more than any other country in the world over this timeframe.

The Dawn of the Megacity

People are not only flocking to cities, they are flocking to megacities – urban conglomerations with more than 10 million people.

In just 40 years, the total amount of megacities will quadruple, gaining nearly 600 million residents in the process:

Year# of MegacitiesPopulation% of Urban Population
199010153 million7%
201023370 million12%
203041730 million14%

With billions of new people living in urban areas – and many of them living in megacities – we will have to rethink how our cities are designed and engineered.

And as this happens, the city as we know it will be revolutionised.

The Urban Opportunity

Rapid urbanisation will create both opportunities and challenges for society, and a plethora of investment possibilities in the process.

As global cities become more integrated with technology, new business models will emerge as cities become smarter, denser, and more connected.

These potential opportunities include:

  • Smarter cities
    Cities will embrace technology to improve services and infrastructure, adding tech-driven features like smart lighting or real-time traffic updates.
  • New infrastructure
    Cities and companies will invest heavily to build next generation infrastructure, such as data centers, green energy, and citywide WiFi.
  • A focus on personal security
    With higher crime rates in cities than rural areas, governments will employ elevated levels of surveillance on citizens in cities. Increasing connectivity means that every activity is logged and monitored.
  • New services
    As cities become more connected, non-traditional players – such as cybersecurity experts or cleantech engineers – will be needed as a part of city planning processes.
  • No car ownership
    A lack of space and the rise of autonomous cars will mean fewer people will own a car, preferring to use ‘summon-able’ services instead.
  • New healthcare systems
    As population density grows to unprecedented levels, existing healthcare systems will need to be radically overhauled to deal with this influx.

Rapid urbanisation will have a wide-ranging impact on global economics, demographics, and society as a whole.

As rapid urbanisation and other megatrends collide and feed off each other, there’s no doubt that even more thematic investment opportunities will be created.
